WILLIAM ADELMANN, 0F CITY ISLAND, NEVI YORK; ALICE ADELMANN AND WILLIAM D. SPORZBORG EXECUTOIRS OF SAID Ji/"ILLIALW ADELIHANN, DECELASED BOAT Application filed October 24, i928.

The present invention relates to an improvement in boats, and has for one of its objects the provision of a boat of simple and novel construction, care being taken at the same time to provide a structure or construction which will be absolutely safe, my improved boat being intended primarily for pleasure purposes.

.fr further object of my invention is the provision of a boat of the knock down type,

`the same being constructed so that it may be taken down very quickly and the parts stowed in an Iautomobile, for example, and as quickly assembled again.

In general, my invention provides a boat comprising four floats, two at the forward part of the structure and two at the rear, a frame of light metal, such as aluminum tubing, for example, being attached detachably to these floats, whereby the floats and frame may be assembled or knocked down7 very quickly.

Intermediate the two sets of floats I provide a seating and control arrangement very simple in construction and readily detachable. This seating and control arrangement may also be very quickly assembled as a unit.

In addition to all of the foregoing, I provide for causing the front end of the boat to rise or lift as the speed of the boat increases, additional apparatus for effecting this result being provided and controlled from the operators seat. This last mentioned apparatus is useful as braking mechanism in bringing the boat to rest.

I have also provided for reducing as far possible excessive heeling of the boat, this apparatus being automatic in operation and requiring no attention on the part of the operator.

@ther and further novel features of the invention will be pointed out hereinafter.

In the accompanying drawings, wherein I h ave illustrated an embodiment of my invention, Fig. l shows the same in side elevation;

F 2 is a section taken on the line 2-2 of Fig. l; and

l11 3 is a. plan view.

Referring to the drawings in detail, my improved structure comprises four floats l, 2, 3

Serial llo. 314,672.

and 4, the floats l and 2 being mounted at the forward part of the boat and 8 and 4 at the rear. 'lhese four floats constitute the buoyant members of the boat.

Various materials may be employed in the makeup of the floats but in any event the floats are, in accordance with my invention, constructed of solid material made up of one piece or laminated as desired, as distinguished from airnlilled pontoons. This is for safety purposes, pontoons when punctured allowing the pontoons to lill and the boat to sink, whereas puncturing or injury to one or even all of the floats of my structure will not n'iaterially affect the buoyancy ofthe craft.

The material which I prefer to employ is balsa wood, although the floats may be constructed of cork sheets. As a matter of fact other woods are suitable, balsa and cork being mentioned merely by way of example. I have shown each float4 as made up of laminations, although as above mentioned they may be formed out of the one piece, both forms, however, coming within the expression solid structure.

For the purpose of insuring a speedy construction without necessitating the use of a powerful power plant, I prefer to cut back the forward end of each float, as indicated at 5. In addition to this and for the purpose of causing the floats to plane when moving forward, I concave the bottom of each float, as shown at G in Fig. 2, the concave portion eX- tending as will be understood, longitudinally of the floats.

Extending lengthwise of the entire structure and overlying the floats l, 2, 3 and 4 are side frame members 7 and 8, one at each side of the structure. its above mentioned, these members may be made of very light weight material. such as aluminum tubing, for instance. jThe frame member or side frame piece Y is secured to the forward float l and rear float 3 by bolts 9,' l0 and l1, l2, respectively, while the side frame member 8 1s secured to the forward float 9, and rear float 4 by bolts 13, 14 and l5, 16, respectively. These bolts pass down through the floats, and not only do they secure the side frame members in place, but they also secure the laminations bers instead of Ithumb nuts 24.

for convenience are carried by the bolts 9,

l0, etc.

Finally, thumb nuts 18 are screwed upon the upper eiid of eachof the retaining bol ,-3, and this will hold the side frame members securely in position while at the same time pro viding a structure which may be readily @knocked down or taken apart.

vThe floats are permitted to pivoty in addition to the motion permitted by the springs 17, by providing pivots i) intermediate 'the sideframes and floats.

At the forward end of the side frame inembers 7 and 8 and beyond the forward ends of Vthe forward iioats l and 2, I provide a bumper 19, which may consist of a metal tubing detachably secured to the side frame members 7 and 8 in any convenient fashion.

At the rear ends of the frame members 7 `and 8 I provide a similar bumper 2O and deltachably secured tothe ends of the members 7 and 8 beyond the rear endsof the ioats 3 and'4. Y

For the purpose of bracing the structure lI`iiiay employ cross pieces 2l and 22 held to the vside frame members 7 and 8 by bolts 23 which merely pass into these side frame niemgoing through the floats, and

The brace 22 which is at the rear of the structure about midwayV of the length of the floats 3 and V4, not only functions as a brace rmember but also as a support for an outboard vmotor 25, by which the boat may be propelled.

This outboard motor may be of any of the well-known types of motors and is so mounted on the brace v22 as to swivel in a manner kwell understood to enable the boat to be steered. For the purpose of swiveling the motor 25v I provide ropes or cables 26 and 27 vpassing about the framework of the motor in' opposite directions and secured to the Y framework, these cables beingbrought forrist wardy to the steering column 28. Movement of the'lsteeringwheel 29 will cause tne motor 25 to swivel in one direction or the other, depending upon the direction the wheel 29 is moved. l Y

As above' mentioned, means arejprovided 'for preventing excessive heeling of the boat,

and to thisend I provide or rather I attach fins 30 and Sito the inner sides of the floats l and 2. In addition I attach similar fins 32 and 33 to the inner side of the rear floats 3 and 4 respectively, and to the outer side of these latter floats I attach similar fins 84 and 35, respectively. TheseA fins-are mounted on bolts 36, and each fin is provided with an upstanding portion or extension 37 through which the bolt passes. rlhis extension 37 is slotted, and while the fins are held against a tipping movement they are permitted by reason of this slot and bolt construction to move upwardly or downwardly, as the case may be, and as the floats settle, due to an increase in speed of the boat, the fins will auloinatically move upwardly, so as always to be in proper position to perform the function of preventing excessive heeling of the entire structure. I might say that I have found that these fins also add somewhat to the speed of the boat iii that they will naturally tend to cause the floats to plane as their speed increases.

As above mentioned I also provide mechanism between the forward fioats 1 and 2 which may be employed as a brake in bringing the boat to rest and which may also be employed in causing the boat to plane. This mechanism comprises two flat plates 3S and 39 extending longitudinally of the structure and secured to a rod 4() extending transversely of the structure. The rod 40 has a lever 41 secured to it, this lever in turn being secured to a rod 42 extending rearwardly to within reach of the operator and is controlled from the operators seat by control lever 43. Manipulation of the lever 43 will cause the plates 38 and 39 to be raised and lowered and obviously by proper manipulation of the lever 43 the rear ends of the plates 38 and 39 may be dropped, so that the plates will stand almost vertically and thereby function as a braking mechanism to bring the boat to rest.

The seating compartment of my improved apparatus is also quickly removable and coniprises longitudinally extending frames 44 and 45, extending longitudinally of the structure, and cross pieces 4G and 47 detachably secured to the main or side frame menibers 7 and 8 through uprights 4S fastened to the side frames by bolts and thumb nuts.

The seats or chairs are designated 49 while 50 designates a canvas well within which the seatsv and steering mechanism are mounted. This entire structure may be removed from the side frames 7 and 8 as a unit.

From all the foregoing it will be seen that I have provided a boat of new and novel construction and comprising four floats, two at each end thereof, with a seating compartment mounted between the two sc ts of floats.

It will be seen, furthermore, that the two sets of floats are composed of a material which has a high degree of safety in that puncturing of the same is impossible, those floats being solid structures so that there is no danger of the boat sinking as in the case of that type of craft employing air-filled pontoons.

It will be seen, furthermore, that the entire structure is so assembled that the same may be quickly knocked down and packed in a small space. As a matter of fact the same may be taken apart and very readily carried in any ordinary automobile. It will be apn preciated, furthermore, that the boat may be as quickly assembled.

It will be seen, furthermore, that I have provided means for absorbing as far as pos sible the shock of the Waves striking the boat, and means for preventing heeling of the boat excessively as well as means for bringing the boat quickly to rest.

While I have described one embodiment of my invention it is to be understood that changes may be made therein without departing from the spirit and scope of my invention.
